HP Pavilion f1503 desktop LCD Flat monitor turns on for about 2 seconds then turns off, what do I solder?

Ok, one thing you could try is to ditch the power brick.  I have a Tevion LCD which just went into random off behaviour.  I swapped it out with another and decide to have an experiment on it.  I chopped off the power supply brick, soldered that cable to an old computer fan piggyback adaptor (it just means no cutting up cables coming from the computer PSU) and it worked, no random off-ness.

If it is something internal to the monitor, then that's out of my league, sorry.

Nobody can answer that but you. The fact that you're spelling solder wrong tells me that this is probably the first time you've ever had to do it, or anything else related to electronics. Before you can fix it, you need to learn about electronics troubleshooting. The best way to learn is by doing a lot of reading and building circuits of your own. I highly recommend one of the project kits from Radio Shack. Or, you could take some classes. But if you're not interested in electronics and how things work in general, then it's not really worth your time. The test equipment alone would cost more than a new monitor. There's a patience factor to it. Without that, it can be very frustrating at times. It comes naturally for very few people. Who knows, you may find you like it; but there's a lot more to it than just melting a little lead. If I had statistics on the failure modes of that particular model, I could tell you what has a chance of being wrong; but I can't tell you where to solder or what to replace in your particular monitor without working on it myself. Maybe it's not the answer you want or the answer you were looking for; but it's the truth nonetheless.
thanks alot for pointing out the solder mispell. what great help...and thanks for the input as all are welcomed...have a nice day.

sounds like the power supply is having issues.. probably a blown capacitor.
